Digital temperature sensors DS18B20

DS18B20 – calibrated digital thermometer with 1-Wire-Interface and the bit conversion, capable of adjustment. The range of measured temperatures from -55 ° C to +125 ° C. Read on chip digital code is a direct result of the direct measurement of temperature and does not require additional changes. Programmable user-built ADC resolution can be changed in the range from 9 to 12 bits of source code. Absolute error converting less ± 0,5 ° C in the range of controlled temperatures -10 ° C to +85 ° C. Max full 12-bit conversion ~ 750 msec. Nonvolatile memory chip temperature settings provides a record of arbitrary values ??of the upper and lower control threshold. In addition, the thermometer has built-logical mechanism priority alarm master 1-Wire-network on the fact of the temperature controlled by one of the selected thresholds. Unit 1-Wire-Interface component is organized so that there is a theoretical possibility of addressing an unlimited number of such devices in a 1-Wire-network. The thermometer has a unique 64-bit registration number (group code 028N) and provides the ability to work without an external source of energy, but due to parasitic power 1-Wire-line. Power chip via a separate external output is voltage from 3.0 V to 5.5 V. The thermometer is placed in the body of transistor TO-92 or 8-pin SO casing for surface mounting (DS18B20Z), or 8-pin housing micro-SOP surface Mount (DS18B20U).
Sensor can be conected to Arduino, Raspberry Pi, ESP8266, etc.
